ARMBRUST, F MIDDLETOXVN, NEW YORK, ASSIGNOR TO INTERNATIONAL LIFE SAVING WATER MAKING CUP CORPORATION, OF WASHINGTON, DISTRICT OF COLUMBIA, A CORPORATION OF DELAWARE LIFE-SAVING WATER-MAKING TWIN our Application. filed January 11, 1927. Serial No. 160,497.

This invention relates to life saving apparatus 1n the form of a moisture condensmg and water collecting device of the twin cup type, and has for its object the provision of a simple, efficient and. convenient cup construction whereby the moisture of the exhaled breath is condensed and collected in a separate cup for use in emergencies as in cases of shipwreck, in desert places or wherever conditionsare likely to cut off the supply of drinking water.

Another object includes the provision of a construction wherein the moisture condensing elements are arranged and contained in a separate compartment from which the collected moisture is allowed to drain into the twin water-holding compartment. A further object of this invention includes a construction which will float in water. My construction is further compact, durable and provided with a reservoirfor holding water which can be drunk. I further provide a construction which is readily attached to a life-saving belt, and which has means for separating the saliva from the condensing and condensed water.

Other objects will appear hereinafter and I attain these objects by the construction illustrated in the accompanying drawings in which,

Fig. 1 is a view of my improved device with the complementary cover of Fig. 3 removed.

Fig. 2 is a view taken on the line 2-2 of Fig. 1 with the complementary part of Fig. 3 in place.

Fig. 3 is a view of the complementary part or cover ofthe condensing compartment, and the water holding compartment shown in Fig. 1.

' Fig. 4 is a view taken on the line 4-4 of Fig. 1, when the complementary part of Fig. 3 is in place, and 1 I Figs. 5 and 6 are views taken respectively on the lines'55 of Fig. 6 and 66 of Fig; 5.

The same numerals refer to like parts throughout the several views.

It is known that breath leaving the body of a person is saturated, that is, it contains all the moisture that it can hold at the body tem perature, which. normally is a little over 98 age in life belts and the like. walls of the'opposite sides and 21 of cup A,

degrees F. Experiments show that at body temperature the amount thus given olf by the average healthy individual is from 12 to 20 ounces in every twenty-four hours. In cases of shipwreck or in desert places with no F drmking water, the condensed water obtained tent, the moisture content ofrespired air for shipwrecks or the like. To this end, I provide twin cup construction (A, B) which is provided with means for receiving and passing respired airwith ease, so as not to obstruct breathing, while at the same time the moisture content is most effectively separated and finally collected in the separated twin cup (B) from which it is readily obtained for drinking. In order to extract the moisture, as completely as possible, I provide a large condensing surface, so arranged and constructed as will expose the respired air to the best advantage. In a preferred form of construction, my improved cup comprises a large breath receiving and condensing compartment or twin cup (A) having integrally attached thereto the water receiving compartment or reservoir (B) usually of smaller capacity. These cups or compartmentsv are preferably flattened to thereby provide, not only for quick cooling, but also for easy stor- To the inner there are attached the condensing fins 22 and 23. Fins 22 are soldered or otherwise secured to walls 20 and to the central partition 24. while fins 23 are similarly secured to wall21 and the central partition 25. In other words the transverse partition 24=25 shown in Fig. at is composed of. two portions, a double walled portion 24 attached to side 20 which telescopeswith a double wall 25 attached to side 21. The outer ends 26 and 27 of all the fins are spaced from the wall of the cup, so. as to permit free passage of condensed moisture from the fins which slope from the center outwards, see Fi s. 1 and 3. The condensing compartment communicates with the reservoir B by an aperture 30 to permit the condenscd water to collect in the reservoir. The partition plates 24 and 25 interlock and form an air tight partition wall, thereby dividing the cup chamber into two separate compartments.

As is best shown in Figs. 1 and 2, a breathing tube 31, having a mouth piece 32 is suitably fastened to a holding member or sleeve 33 in cup A. Sleeve 83 is provided with an outlet 34. for allowing free passage of the breath into and through the condensing chambers. This sleeve is also in direct communication with the saliva collecting tube 35 which extends through both cups A and B, and is secured in cup B by suitable means as by solder or by welding. The open end 86 of this tube is closed by a suitable screw cap 87 which is held by a guard chain 38. A similar screw cap 89 on the water outlet tube or tap 10 permits water to be drawn as required in emergencies. The condensing cup is also supplied by an egress valve for free outward passage of the moisture deprived air through the outlets 51.

In Figs. 5 and 6, I have shown a disk type of twin-cup construction (E, F) wherein corrugated disks 80, 81 and 82 serve as moisture condensing plates within cup E. Plate has an extension 83, which is connected with the lower part of the respiration tube 84. This tube has a breath outlet 85 for admitting the breath into the space formed by the bafi'le 80 and the cup wall 86. A cut-out sector portion at the lower part of plate 80 permits free passage of the breath to the inner compartment formed between plates 80 and 81. Plate 81 carries, mid-way, the saliva tube 87, which extends from the lower end of tube 84 to the outlet 88 in cup F. This plate has a cutaway part at the top whereby breath is permitted to enter from the second compartment between plates 80 and 81 to the third compartment between plates 81 and 82. Plate 82 is sealed at the top (and sides), and has a cutaway portion in the lower part at 89, through which breath enters the final chamber between plate 82 and the rear outer wall 90. From this chamber the breath escapes into the open air through the valve 79. The corrugations of plates 80, 81 and 82 aflord better condensing surfaces, and the condensed water is collected in the reservoir cup F. A thin plate 91 is carried on the saliva tube 87. This plate is thin and flexible, and in a preferred form of construction, it is soldered or welded on the salivatube, and thus serves as a breakwater to keep the condensed water in the reservoir cup, and to prevent it from being blown out through the valve.

In the constructions described herein, by way of illustration merely, the moisture laden breath enters on one side of the cup or compartment and passes back and forth, or in and out in a tortuous passage, over the moisture condensing plates which are arranged to be most effective in quickly condensing and collecting the moisture. Breath is thus deprived of its moisture in a most eflicient manner and the condensed water thus collected and used in emergencies may mean a difference of life and death.

Having now described my invention, what I claim as new and useful and desire to secure by United States Letters Patent is:

1. A moisture condensing and water collecting device comprising interconnected compartments, one of said compartments having condensing devices arranged symmetrically and in duplicate.

CHARLES W. ARMBRUST.
